Hi- appologies if this has been covered a million times before, but I am struggling to find anything on it:

I would like to measure C02 for IVA emmisions prep at home. Is it possible to use my AEM Wideband AFR Lambda UEGO Gauge to do this?

Otherwise, how can I do it bar taking it down the local MOT station?

Thanks in advance.

Matt

An oxygen sensor can't measure CO2.

well one way would be... , but it is flawed,
inhale all the exhust fumes, if your still alive after 2 mins, it will be fine

PLEASE DONT DO THIS!!

It's CO, not CO2, which is tested at IVA by the way.

okeydokie...cheers for the reply's.

Is there a way of doing it at home then?

You can't measure CO, or CO2 with a lambda probe, but you should be able to get the mixture correct with a lambda probe, which should give you the correct CO2 and CO.
